dt_hoist {tidyfast}

Hoist: Fast Unnesting of Vectors

Description

Quickly unnest vectors nested in list columns. Still experimental (has some potentially unexpected behavior in some situations)!

Usage

dt_hoist(dt_, ...)

Arguments

dt_

the data table to unnest

...

the columns to unnest (must all be the sample length when unnested); use bare names of the variables

Examples

library(data.table)
dt <- data.table(
  x = rnorm(1e5),
  y = runif(1e5),
  nested1 = lapply(1:10, sample, 10, replace = TRUE),
  nested2 = lapply(c("thing1", "thing2"), sample, 10, replace = TRUE),
  id = 1:1e5
)

dt_hoist(dt, nested1, nested2)
